(2) Low magnetic susceptibility was observed at a high backscatter intensity patch. WebHydrothermal Vents are large, narrow thermal structures located in the Arctic Kelp Caves, Crystal Caves, Deep Twisty Bridges, and the underwater portion of the Glacial Basin. The area around Hydrothermal Vents is generally charred, showing their extreme heat output.
Web[10] On Earth, hydrothermal circulation in the oceanic crust accounts for approximately 50% of the total heat flux from cooling lithosphere less than 60 m.y. in age; at greater ages, thick sediment cover inhibits hydrothermal flux [Stein et al., 1995]. High-temperature ( 350 C) hydrothermal venting accounts for 3–15% of the total hydrothermal
